The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that are no longer considered amphibians. Modern forms are excluded from this list.
The second largest prehistoric pinniped is Gomphotaria pugnax with a skull length of nearly 47 cm (19 in). [150] One of the largest of prehistoric otariids is Thalassoleon, comparable in size to the biggest extant fur seals. An estimated weight of T. mexicanus is no less than 295–318 kg (650–701 lb).

But in later studies, animals of this species estimated to have grown to at least 23.2 cm (9.1 in) (snout-vent length), which is around the size a modern African bullfrog can reach. [5] The head of Beelzebufo was very big, [ 5 ] and bones of the skull roof show a rugous external surface, indicating at least parts of the head may have borne bony ...
Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
The early reptile-like amphibians were mostly aquatic, the first highly terrestrially adapted groups being the Seymouriamorpha and the Diadectomorpha. The seymouriamorphs were small to medium-sized animals with stout limbs, their remains are sometimes found in what has been interpreted as dry environments, indicating their skin had a water ...

The largest South China giant salamander, which researchers said is likely the largest amphibian ever recorded, lived during the first half of the 20th century and was housed at the London Zoo for ...
Some evidences, including the fossils of some smaller temnospondyls bear tooth marks made by mastodonsaurid-like animals. It is very likely that mastodonsaurids caught their food like the living Giant Salamander, waiting until the prey came near, then quickly opening their enormous mouths and swallowing them prey whole.
